Bullshit. It's Vince's company and he can put whoever he wants in the main event. Just admit, the fans nowadays are so greedy they want everything their way and if they don't get it, they throw a temper tantrum instead of stop watching. You don't hear Game Of Throne fans going on strikes and heckling the writers because their favorite character died on the show. Why do wrestling fans get to be so entitled?
You give the paying customer what they want, or they have the right to bitch about it. "Vince" is not above that. This is no different than any other company - it just so happens WWE is in a position to receive that feedback more immediately or directly. Game of Thrones isn't held in front of a fucking live audience, or you can bet your ass the arena would be filled to capacity with nerdy obsessives complaining when something didn't go the way they wanted.
People complaining about last night's crowd are being contrarian against the contrarians because I guess being "anti-smark" is the new cool thing to do. that. We're not going back to the 80's. Last night's fans are the most devoted that the company has, so they are going to be the most passionate about what they see presented, be it positive or negative.
But nah, let's go back to your apparent dream scenario of apathetic, just-shut-up-and-watch audiences we get most weeks on Raw. I'm sure it won't take more than another week before we're back to getting either zero reaction or (if they are feeling inspired) "WHAT" during promos.
